Frostbite from temperatures above freezing

AIUI, frostbite is defined as body tissue having literally froze at some point, which would indicate it’s impossible to get frostbite from temperatures above freezing. But if a part of the body is exposed to temperatures of 1-2 degrees Celsius for long enough, it would surely sustain injury as well. What would that be if not frostbite?


How about “Nonfreezing Cold Injury”?

BTW the above was quoted from UpToDate

Trenchfoot is a frostbite like condition that can occur with tissue submerged in temperatures as high as the 60s.

Frostbite can also occur at ambient temperatures near but above freezing where wind chill produces skin temperatures below freezing, particularly if the skin is wetted by sweat, rain, et cetera, hence the need for wicking layers and water barriers in cold weather apparel.


Oh ok thanks.

I read that a kid once got esophageal frostbite by swallowing a piece of dry ice. Wonder if someone can get esophageal chilblains (or whatever term) from eating, say, vast quantities of ice cream or crushed ice?

Sort of related, but the index finger on my left hand gets numb and white at temperatures above freezing. It sometimes occurs in air conditioned rooms. I believe it’s Raynaud syndrome.

I have Raynaud’s in my hands and feet, and that sure sounds like what I experience, except that mine turn white and numb, then blue, then red. In the white, numb stage, I can get cuts that I don’t know about until my hands reestablish blood flow and I start bleeding.

I’ve also had chilblains lupus on my toes. Lupus affects my circulation, and my classroom was cold enough in winter that some students wore coats.
